IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 103,013, dated May 17,1870.

To all whom it may concern:

Be it known that I, G. W. H. OALVER, M. 1)., of Burlington, in thecounty of Burlington and State of New Jersey, have invented a new anduseful Improvement in Automatic Cartridge-Ejectors; andIdo herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification. v

Figure 1 is a side view of a revolver to which my improvement has beenattached. Fig. 2 is a cross-section of the same, taken through the line00 00, Fig. 1. Fig. 3 is a detail view of the rear end of the cylinder.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cartridge-ejectordesigned for attachment to all kinds of revolving or cylindersmall-arms, which shall be simple in its construction, automatic in itsaction, and effective in itsoperation; and it consists in thecartridge-ejector constructed and operating as hereinafter more fullydescribed.

A represents the stock; B, the frame; 0, the cylinder; D, the barrel;and E the hammer, about the construction of which there is nothing new.

To the frame B, at the rear end of the cylinder 0, are attached or uponit are formed two thin pieces, F, parallel with each other, to form agroove or way for the sliding block G, the forward end of which .isprovided with aclaw, H, so formed as to fit upon the body of thecartridge-shell in front of its rim or flange, so as to draw out thesaid shell as the slide G is drawn rearward.

The forward edge of the claw H should be beveled or rounded off to causeit to slip over the rim of the cartridge as the slide G is pushedforward. The rear end of the cylinder 0, over each chamber, should berecessed to allow the claw H to pass over the rim of the cartridge tothe forward side of said rim as the block G is pushed forward.

I is a spring attached to the upper piece or strip, F, or to the frameB, in such a position as to rest upon the upper end of the claw H whenthe slide G is pushed forward to force and hold the claw H down upontheneck of the cartridge. The spring I is not absolutely essential, butI prefer to use it to insure the olaws always takinghold of thecartridge-shell. The slide Gis operated from the hammer E by the leverJ, which is pivoted to the frame B, and the upper end of which ispivoted to the said slide G. The lower end of the lever J is connectedwith the hammer E bya short connecting bar or link, K, as shown inFig. 1. By this construction, when the hammer E is drawn back to cockthe arm the slide G is pushed forward to grasp the shell of thecartridge last discharged, so that as hammer is thrown forward indischarging the arm .the forward movement of the hammer operates thelever J, draws back the slide G, and draws out the shell of thecartridge.

It should be observed that when there is not sufficient room between thepivoting point of the lever J and the rear end of the cylinder 0 toadmit of loading from the rear, it will be necessary to cut away aportion of the base of the frame B-npon the opposite or left side of thearm to admit of loading upon that side.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent For removing the shell of a discharged cartridge fromthe rear of the cylinder, the slide G, claw H, lever J, and link K, incombination with the hammer of the arm, when arranged to' operatesubstantially as hereinbefore set forth.
